<h1>Importing django.db.models.fields<a class="headerlink" href="#importing-django-db-models-fields" title="Permalink to this headline">¶</a></h1>
<p>In Django, models are defined in <code class="docutils literal notranslate"><span class="pre">django.db.models.fields</span></code>. However, for convenience they are imported into <code class="docutils literal notranslate"><span class="pre">django.db.models</span></code>. Django’s standard convention is to use <code class="docutils literal notranslate"><span class="pre">from</span> <span class="pre">django.db</span> <span class="pre">import</span> <span class="pre">models</span></code> and refer to fields as <code class="docutils literal notranslate"><span class="pre">models&lt;some&gt;Field</span></code>. To improve readability and maintainability of your code, change your import statement and model definition.</p>
